Abstract
995,435. Forming selvedges. R. DEWAS. Feb.20,1962 [Feb. 24, 1961; Oct. 17, 1961; Feb. 13, 1962], No. 6470/62. Headings D1E and D1K. A selvedge forming-device wherein a needle 8 inserts a loop, which is held in the shed by a plunger 14 as the needle 8 withdraws, has means to render inoperative the needle 8 and plunger 14 so that a loop need not be inserted at each pick. The main shaft 18 carries a cam 19 having followers 27, 43; the follower 27 reciprocating a spring loaded rack 6 which moves a segment 32 to oscillate the needle 8, and the followers 43 rocking spring loaded levers 45, 49 to insert the plunger 14. A cam 56, rotated from the main shaft 18, oscillates levers 58, 52, 65 and a segment 57 having heels 71, 72. In the position shown in Fig. 7 the segment 57 has been oscillated so that the followers 27, 43 have ridden on to the heels 71, 72 and thus the cam 19 does not operate the needle 8 and plunger 14. The gear ratio of the main shaft 18 or the shape of the cam 56 are arranged to allow, e.g. one selvedge insertion every third pick. Other ratios are described. In place of the cam 56 a gear box may be provided to vary the reciprocation of the rack 6 and oscillation of the plunger 14. A selvedge having an intermittently inserted loop c<SP>1</SP> is formed as shown in Fig. 3, the end of the loop may be out in the fabric. Specification 868,437 is referred to.
